Athlete Health Study

About The Study

Are you interested in contributing to research assessing perceived respiratory and athletic capacity? Join our exciting study to better understand the impact of a new investigational product, L Max, on respiratory cleansing in healthy adult athletes 18 to 60 years old. L Max is purposefully designed to stimulate cleansing of the lung to remove particulates such as dust, smoke, and pollen.

After signing up, you will take a short online questionnaire to find out whether you qualify for the study. After qualification, you will complete brief online surveys about your medical history and medications. During the study, you will answer daily and weekly online surveys, use an Oura Ring, perform spirometry assessments, complete and record training sessions. Spirometry is a test that shows how well your lungs are working by blowing as hard and fast as you can into the tube on the spirometer. The data you provide will be made anonymous, and the analyzed results will be shared with you and the research scientists. Joining this study is completely voluntary.
